COMBINED WRENCH AND SCREW-DRIVER.

SPECIFICATION forming part of Letters Patent No. 411,190, datedSeptember 1'7, 1889.

Application filed April 27, 1889. Serial No. 308,802. (No model.)

To all whom it may concern.-

Be it known that I, BURR ALBERT HAINES, a citizen of the United States,residing at Smithville, in the county of Burlington and State of NewJersey, have invented certain new and useful Improvements in CombinedWrenches and Screw-Drivers; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to certain new and useful improvements in combinedwrenches and screwdrivers; and the nature thereof consists in securing ascrew-driver in the handle of a wrench and in providing means wherebythe said screw-driver may be locked in position for eithertransportation or use, as will be hereinafter more fully described andclaimed.

Referring to the accompanying drawings, in which corresponding parts aredesignated by similar letters, Figure 1 is a perspective View of myinvention. Fig. 2 is a longitudinal section thereof on the line a ofFig. 3. Fig. 3 is a cross-section on the line 'y y of Fig. 2, and Fig. 4is a detail of the screwdriver.

The rounded post A of the lower jaw 13 of the wrench has screwthreads Ctupon its upper end, while the same end is also provided with alongitudinal slot a. The handle 0 is attached to the upper jaw B, andhas in its central part the longitudinal rounded cavity 0 to receive thepost A. A longitudinal slot 0 is formed in the upper end of the handle,corresponding to the slot at in the post A, while a recess 0 is alsoformed in the said handle extending from side to side thereof,intersecting the longitudinal cavity 0. A thumb-nut D is placed in therecess 0 working upon the screw-threads or. upon the post A, and thus bythe revolution pf the said nut the jaws B and B may be caused toapproach or recede. The thumb-nut D has also an interior groove cl onone side thereof, and has upon its outer surface depressions or marks61, which, when in line with the correspond ing depressions or marks 0upon the handle 0, indicate that the groove (1 is in the same plane asthe longitudinal slots to and c in the post A and handle 0,respectively, and toward the back of the handle in that plane.

The screw-driver E has upon its rear end a nose 6, while upon the sameside as the nose, but more toward the middle thereof, is the lug c. Theforward end of the screw-driver has a slot 6 through which passes thescrew 0 in the handle 0, for the purpose of guiding the screw-driver,which is, with the exception of at nose 6, lug c, and slot e narrowenough to work freely within the smaller inside diameter of the nut D.

The screw-driver rests, when not in use,

within. the slots at and c of the post A and handle 0, that portionmarked 6 in Fig. lbeing surrounded by the nut D, while the lug e restsupon the under surface of the said nut, the nose projecting through theslot 0 in the handle to the surface of the back thereof, and thus servesas a means for moving the screw-driver.

When it is desired to use the screw-driver, the nut D is turned untilthe marks (1' and c coincide, when the nose c may be pushed to ward theupper end of the handle. In this operation the lug c will pass throughthe interior groove d of the nut. After the screw driver has been pushedout to its full extent the nut D may be turned, when thel'ug (2' willbear upon. the upper surface of the nut, thus preventing the return ofthe screw-driver to within the post A, and it is in this position thatit is represented in Fig. 1. When it is desired to return thescrew-driver, the abovedescribed operation is reversed and thescrewdriver will occupy its position as first-above described, in no waypreventing the rotation of the nut D and the proper manipulation of thejaws B and B of the wrench.

The tool hereinbefore described may be put together as follows: The nutD is first placed in position in the recess 0 and the screwdriver placedin the longitudinal slot of the handle and passed through the nut. Thepost A is then inserted in the longitudinal cavity of the handle in sucha position that its slot is in the same plane with that of the handleand with the screw-driver. The nut is then 1 rotated, drawing the jawstogether, and the screw 0" is inserted in its hole.

Having thus described my invention, whatI claim is-- 1. In a combinedwrench and screw-driver, the combination of a post carrying a lower jawand having a longitudinal slot therein, a handle carrying an upper jawand having a longitudinal cavity and slot therein, a recess in the saidhandle intersecting the said cavity, a thunib-nut in the said recessengaging the said post, and a screwdriver contained in the saidlongitudinal slots in the post and handle, as and for the purposesdescribed.

2. In a combined wrench and screw-driver, the combination of a postcarrying a lower jaw and having a longitudinal slot therein, a handlecarrying an upper jaw and having a longitudinal cavity and slot therein,a recess in the said handle intersecting the said cavity, a thun1bnut inthe said recess engaging the said post, an interior groove in the saidnut,

and a screw-driver having a lug upon its edge adapted to pass throughthe said interior groove, the said screw-driver being contained in thesaid slots in the post and handle, as and for the purposes described.

In a combined wrench and screw-driver, the combination, With an upperand a lower jaw B and B, respectively, of a rounded post A, attached tothe said lower jaw B, a longitudinal slot a in the said post A andscrewthreads at thereon, a handle 0, attached to the said upper j aW B,a longitudinal cavityc and slot 0' in the said handle 0, a recess 0extending from side to side of the said handle and intersecting the saidcavity 0, a thumbnut D, having an interior groove d, contained withinthe recess a and engaging the screwthreads at on the post A, ascrew-driver E, resting within the slots a and c of the post A andhandle 0, respectively, a nose 6 and a lug e on the said screw-driver, aslot 6 in the screw-driver, a screw 0 in the handle 0 passing throughthe said slot c and marks 01' and 0 upon the nut D and handle C,respectively, all as and for the purposes described.

In testimony whereof I affix my sign atnre in presence of two witnesses.
